Sewer pumps and lift stations for Prescott-area homes.

What an LPSS system actually is

The pump pushes sewage when gravity cannot do the whole job.

LPSS means low pressure sewer system. Instead of wastewater flowing downhill by gravity from the house to a large public sewer main, the home has a private tank and grinder pump. The grinder pump breaks down solid waste and sends the wastewater through a smaller pressure pipe.

That pipe can travel uphill, downhill, and around rock or other obstacles. In some Prescott-area subdivisions, the distance and elevation can make a pressure-sewer system a practical choice. Each home may have its own pump station, which is different from a standard gravity sewer connection.

• Pump tank near the home
• Switch that turns the pump on
• Alarm for high water or other trouble
• Small pressure pipe to the sewer

Why this matters for repairs

Your home’s pump and the public sewer are not the same thing.

A pressure-sewer problem is not always fixed by replacing a pump. The technician needs to understand the private tank, controls, alarm, pressure line, and how that equipment connects toward the shared sewer system. A switch, control, clog, check valve, or pressure-line issue can look like a failed pump until the full system is checked.

We work on private home pump stations and the parts we can reach. A city, sewer district, or utility may need to handle public sewer lines and larger public pump stations. We explain when the trouble appears to be on the home side and when another group may need to be involved.
